Filed: 1975-02-04
Abstract: 1490661 Valves WILLIS OIL TOOL CO 4 Feb 1975 [6 Feb 1974] 4668/74 Heading F2V [Also in Division F1] In a safety shut-off gate valve the valve stem is connected to a piston 45 by a nut 88 in threaded engagement with the stem, the piston being biased outwardly by a spring 46 and subject to control pneumatic pressure to hold the valve open on its upper surface. In the event of the peripheral piston seal 105 requiring renewing the top 108 is removed from the actuator cylinder 22 and the nut 88 is unscrewed until the spring 46 pushes the piston out of the upper end of the cylinder. The seal 105 can then be replaced and the actuator reassembled. The actuator cylinder 22 is screwed to the boss 24 on the valve housing and can be changed to suit the fluid pressure in the flow path 12 which is controlled by an apertured gate 36 sliding between opposed seats 32 and guided by pins 41 on the gate engaging the sides of valve chamber 14. The valve stem 38 is connected to the gate 36 by a T-shaped head 39 and a complementary slot 40 and is sealed in a bonnet 15 by a packing 55 formed of a plurality of packing rings 60 between a pair of rings 62, 64. If the normally closed passage 42 is opened to vent the chamber 14 grease can be forced into the chamber through the passage 78 and apertures 76 in the ring 64. If the valve is closed so that the valve stem surface 54 seats on the surface 52 of the bonnet and the actuator and gland 58 are removed the packing 55 can be ejected by fluid pressure admitted to passage 78 or a plastics can be injected to repair the packing. Leakage past the packing 55 is visually indicated by fluid emerging from the passage 70. A manual actuator (Fig. 4, not shown) can be mounted on the boss 124 of the actuator and comprises a handwheel operated screw in a fixed nut abutting through a thrust bearing the end 118 of the valve stem.

Title: An oscillatory armature relay actuated by impulses, more especially a change-over relay for multiple-tariff meters
IPC: G01R11/56
Filed: 1941-04-25
Abstract: 548,715. Electrically-tripped switches. LANDIS & GYR SOC. ANON. April 25, 1941, No. 5348. Convention date, June 11, 1940. [Class 38 (v)] [Also in Group XXXVI] An impulse-actuated relay suitable for the changing-over of multiple-tariff meters comprises an oscillatory armature 5 co-operating with poles 1, 2 of a magnet 3 energized by coil 4. When a change-over switch 17 is moved to contact 15, coil 4 is energized over contacts 12, 9 and moves armature 5 to, and beyond, the axis of poles 1, 2 and attracts a detent armature 6 to pole 1. At the same time a pin 10 on armature 5 allows contact 9 to fall away from contact 12 and engage contact 13. The resultant de-energization of coil 4 causes the armature detent 6 to fall and engage a stop 11, so maintaining armature 5 in position beyond the pole-axis. When 17 is moved back to contact 14 the coil 4 is again energized to lift detent armature 6 and free armature 5. which begins to move back under the magnetic force and action of return spring 8. After a small movement, however, pin 10 separates contact 9 from contact 13 and the armature 5 returns to the position shown. The coils 4 of several relays may be arranged in parallel, only one relay having a change-over device. If the actuating device itself produces the impulses, the change-over device may be dispensed with. A resistance may be connected between contacts 13, 14 so as to make the second impulse weaker and ensure the relay keeping in step. The pivot shaft of armature 5 may be connected to a lever operating the change-over pinion of the meter mechanism.

Filed: 1916-04-12
Abstract: 104,071. Wells, F. B. April 12, 1916. Sheafing apparatus. - A sheafbinder harvesting-machine, of the type in which the bound sheaves pass into a pivoting cradle automatically operated to deliver the sheaves to the ground in batches of a predetermined number, has the cradle operated through a ratchet-wheel moved by a pawl actuated by a reciprocating member of the knotting- mechanism, the ratchet-wheel being interchangeable with others provided with other numbers of teeth, and the stroke of the pawl being adjustable to suit the pitch of the teeth on the different ratchet-wheels. The cradle J, J<1> is controlled by the shaft G provided with a crank i carrying a roller i<1>, which rests, when the cradle is loaded, on a stop-arm pivoted on a cam-shaft a. The cam shaft a carries a detachable ratchetwheel b operated by a pawl d actuated from the reciprocating rod F whereby the needle rock-shaft is operated, and a cam c on the surface of which rests a bar g pivoted on the shaft G and carrying a pin engaging in an inclined slot in the stop-arm. The rotation of the cam due to the movement of the ratchet-wheel causes the arm g to be lifted periodically, thus, through the pin and inclined slot connexion, moving the stop-arm from below the roller i<1> and permitting the cradle to open. The sheaves accumulated therein are thus discharged, together with the one that moves into the cradle as the stop-arm is operated. By substituting ratchet-wheel with other numbers of teeth, the number of sheaves discharged at one time may be varied. The bar e carrying the pawl d is provided with a number of openings e', in any of which the pawl pivot may be mounted to adjust the stroke of the pawl to the pitch of the ratchet teeth.
